Acceleration Of Long-Range Ordering in NiCrFe Alloys Using Proton Irradiation

Product Number: ED22-18352-SG

Publication Date: 2022

The extension of nuclear reactor lifetimes beyond 40 years requires the qualification of plant components to ensure performance past their initial design requirements. Nickel-based alloys containing chromium (NiCr) are of concern at these extended lifetimes, as these types of alloys form an embrittling precipitate phase. Below a critical temperature—which is above the normal 300-400⁰C reactor operating temperatures—NiCr alloys form a stable, fully coherent MoPt2-typelong-range ordered (LRO) phase with stoichiometry Ni2Cr.

In-situ Study of Iron Carbonate Formation Kinetics and Pseudo-passivation of Carbon Steel in Aqueous CO2 Environments

This study introduces the design and implementation of a bespoke electrochemical flow cell in combination with in-situ Synchrotron Radiation-X-Ray Diffraction measurements (SR-XRD). The system enables high precision, real-time, in-situ measurements of iron carbonate (FeCO3) evolution on carbon steel in a flowing environment, as well as providing real-time, in-situ corrosion rate measurement through an integrated three-electrode cell. The custom cell is used to examine FeCO3 formation kinetics in a carbon dioxide (CO2)-containing aqueous environment, particularly in instances where the ‘pseudo-passivation’ phenomenon is reported to occur. Linear polarization resistance and anodic polarization measurements were performed in combination with the SR-XRD measurements to establish a detailed understanding of FeCO3 formation in real time and its relation to the corrosion behavior of carbon steel. It was observed that ‘pseudo-passivation’ occurred in conjunction with the growth of a highly protective FeCO3 layer under all conditions evaluated. Magnetite (Fe3O4), an oxide layer often attributed to the onset of ‘pseudo-passivation’, was not observed in these conditions, despite the high limits of detection of the technique.
